Prime Numbers Powerpoint Activity

Children can find prime numbers a difficult concept to grasp in maths.  We have designed a child friendly powerpoint presentation to support teaching this tricky maths skill.  Use this presentation to explain what a prime number is, children can then follow the instructions which explain step by step how to complete a number grid, to help them to find all the prime numbers.  The number grids are also available alongside the powerpoint, these can be printed off for children to complete whilst following the powerpoint presentation.  This is a great teaching tool for KS2 maths.
